How To Use
Bleach Finder: How does it work?
How do I use it?
After a lightening service, a hairdresser always needs to remove the lightener from the hair before toning. The Bleach Finder shampoo is yellow and turns pink when exposed to lightener. If any lightener is in the hair, the lather will turn pink! This means rinse and shampoo again until there is no more pink.

What causes the color to change?
The Bleach Finder formula contains PSP, a pH indicator, that is yellow in acidic conditions and turns pink in alkaline environments. Lightener is very alkaline, so anywhere where lightener particles are still present will cause the lather to turn pink. Will reusing this formula strip the hair? The Bleach Rinse has smart sulfates, along with citric acid, that targets and removes lightener particles, while balancing hair, without over=stripping, so you can keep washing until the formula stays yellow!
